Re: [OpenLayers-Users] BING and OpenLayers
Hate to report this, but setting restrictedExtent does not resolve the
problem. While it seems to prevent the WMS layer from being slid off
the BING basemap permanently, the layers still move asynchronously
when the map is panned. This means that after I am done panning and
let go of the map, I see continued, jerky movement of the layers in
the map interface.
Here's the revised code, with sphericalMercator set to true in the
BING layer instantiation, and restrictedExtent set in the map option.
If you have any additional ideas, I'd be happy to try them. Otherwise
I'll reopen the ticket.
Thanks.

Hi
You need
restrictedExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
20037508.34, 20037508.34)
in the map options, so the WMS layer is restricted to the same extent
as the bing layer.
I closed the ticket as invalid.

Hi All,I'm trying to resolve some strange behavior in my OpenLayers map.
I am using a BING maps base layer, and a GeoJson feature collection

located, and for another, it doesn't move with the BING base layer when I
pan the map.
I am trying to follow the instructions at
http://docs.openlayers.org/library/spherical_mercator.html#spherical-mercator,
which seem to be very well written, but may be slightly out of date? For
example, the doc says to instantiate a new VirtualEarth layer by doing
this:
var layer = new OpenLayers.Layer.VirtualEarth(Virtual Earth,
{ sphericalMercator: true,
maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34)

But the current examples show using this syntax:
var roads = new OpenLayers.Layer.VirtualEarth(Road Map,
{ type: VEMapStyle.Shaded,
numZoomLevels: 21 }
);
In any case, I can't seem to figure out how to apply the projection
instructions that are on the doc. Also, I'm not sure if a projection
mismatch is causing the problem I'm seeing, but I figure it's a place to
start.
Would appreciate some advice regarding how to troubleshoot this.
Hi
http://trac.openlayers.org/wiki/FrequentlyAskedQuestions#WhydontmyvectorfeaturesworkoverGoogleYahooVirtualEarthetc.
(this a link to the old FAQ, as the new one is currently out of order.)
You should use the EPSG:900913 projection in your map and set
sphericalMercator to true in your VirtualEarch layer. See the
spherical-mercator.html example. Also, the vector data (GeoJSON)
should be in EPSG:900913, unless you reproject it client side. If you
use either the fixed or BBOX strategy set projection to the your
data projection (e.g. new OpenLayers.Projection(EPSG:4326)) in the
layer to havr OpenLayers reproject the data to the map projection
before adding it to the layer.
